• IBOutlets are always nil

  - by Jonas

  Hi, In IB I have subclassed the File Owner and the subclass loads my .nib. The subclass itself doesn't need access to the IBOutlets so they're instance variables in another class, which I added as a subclass of NSObject in the .nib. Then I connected the interface elements to that object. But somehow, in the class that "owns" the IBOutlets, they show up as nil. What am I doing wrong here?

• How much memory does a hashtable use?

  - by Michael

  Would a hashtable/hashmap use a lot of memory if it only consists of object references and int's? As for a school project we had to map a database to objects (that's what being done by orm/hibernate nowadays) but eager to find a good way not to store id's in objects in order to save them again we thought of putting all objects we created in a hashmap/hashtable, so we could easily retrieve it's ID. My question is if it would cost me performance using this, in my opinion more elegant way to solve this problem.

• ASP C# How to handle large files from database?

  - by Martijn

  In my web application I am working with files. Some files are very large. I use Response.Write() to write the file to the browser. This goes well for the smaller files, but for large files this can take a while and the bandfwith is fully used. My question is, is it possible to split large documents and send it piece by piece to the browser? I hold the document as a property of an object.

  How should one structure their frequently used non-important functions (conversions, etc) in C# since everything must be contained in an object? Usually I take all these functions and put them in a static Utility class. Is this a good practice? How do most developers do it?

• Parsing values from XML into types of Type

  - by DrLazer

  check this out Type configPropType = configurableProp.getPropertyType(); string attValue = xmlelement.GetAttribute(configurableProp.getName()); configProps[configurableProp.getName()] = attValue; At the point where I am setting the value that got read in from XML it turns out the assigning object needs to be parsed to the correct type for it to work. I need something like. configProps[configurableProp.getName()] = configPropType.ParseToThisType(attValue); Looked around on msdn but its a very confusing place.

• Change the key being pressed with C#

• Which are the most noteable things which make working with Core Date so different than with MySQL?

  - by mystify

  One thing I have in mind is, that datasets in Core Data (or lets say: managed objects) have no ID like known from other databases such as MySQL. Also, they're not in a specific guaranteed order. What else makes Core Data much more "special" compared to working with a relational database like MySQL? Besides the whole object graph persisting and ORM stuff?

• Stack Info button above UIView in Utility App

  - by bgw

  I've started creating a iPhone Utility app (main view and flip view). I want to draw some graphics in the Main view, so I dragged a UIView object onto it. This works, but I find that if I resize the UIView to fill the Main view, it covers the Info button that invokes the Flip view. Is there any way to get the Info button to appear on top of the UIView? In IB? In code?
